I think you have an excellent point here! I prefer 8 hr shifts and prefer the 3-11 shift, which has been pretty much eliminated in my area (SW Florida). As a result, I am taking a huge (50%) paycut to work in a Doctor's office so I can have a schedule that won't kill me! I read a recent article about novel approaches to the nursing shortage and saw that some hospitals are offering "mother's hours"- shorter shifts with more flexible start times. They are reportedly having good success at recruitment and retention by doing so. I know many nurses who love the 12 hour shifts, but the benefit is always framed in terms of having more time away from work... What about having a rewarding and successful time when you are at work? I wonder what the error rate is between 3pm and 7pm, or 3pm and 7am at those hospitals that have all 12 hr shifts running from 7 to 7... I wonder how the patients feel at those times if they need something extra.... just a thought!
